I have a couple different EZ Flash IV models that I've been using for Game Boy Advance, but I've never given any thought to setting them up for DS roms as well. However, I've just been gifted a 3DS... - Is there anything that would prevent me from having both a GBA and a DS setup on one card, simultaneously? (I'd probably opt for the microSDHC model.) - What files do I need to make DS roms function, and where do they need to be placed on the card? Can I just make a \DS directory and put everything there? Is there any file placement I need to avoid? Thanks!
